Feed per Tooth and per Revolution

Calculate Vf, fz and f using standard machining geometric relationships. Supports metric and imperial units.

What do you want to calculate?

Unit system

Positive integer

Result

Fill in all fields to calculate.

Formula used

Vf = fz × z × n

Pure geometric formulas. Recommended feed ranges by material are covered in a separate section.

Variable relationships

Table feed

Vf = fz × z × n

Feed per tooth

fz = Vf ÷ (z × n)

Feed per revolution

f = Vf ÷ n = fz × z

Variables

Vf
Table feed (mm/min or in/min)
fz
Feed per tooth (mm/tooth or in/tooth)
f
Feed per revolution (mm/rev or in/rev)
z
Number of teeth (positive integer)
n
Spindle RPM

This calculator applies pure geometric formulas. Recommended feed ranges by material and insert are empirical manufacturer data and are not included here.
